SPECIFICATION forming part of Letters Patent No. 711,680, dated October 21, 1902..

Agpncanon fuga April 2z, 1992.

To all whom it uta/y concern:

Be it known that' I, CHARLES H. RoUNDs, a citizen of the United States, residing at Passac, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvementsain Machines for Filling Receptacles, of which the following is a specication.

My improvement relates, to machines for filling receptacles with Vfluid and semifluid substances; and the object of my invention is to provide a machine of simple construction whereby several receptacles may be filled simultaneously and quickly. I attain this object'by the device shown in the accompanying drawings, in which- Figure l is a front view of the machine, partly in section. Fig. 2 is an end view of the machine, parts being removed. Fig. 3 is a top view of the cam and cam-bars.

Similar letters referto similar parts throughout the several views.

ais atank or hopper, in the bottom of which I attach the cylindrical fillers b b b b, having mouths b' b. In each of these cylindrical fillers b b b b Iplace a plunger provided with an annular valve-seat p, preferablyof rub-v ber, valve-pluglp, valve-steml, and crosshead ps. The valve-stem p2 moves vertically in a circular opening' in the cross-head p3.' The valVe-stemspZo2 112,102 are prevented from being drawn upward through this openinginV the cross-head p3 by the shoulder p5. The valve-stems p2 192292 p2 are connected at their upper ends to a cross-head or yoke c, by means of which they are caused to move in unison. To the yoke c I attach a driving-rod d in anyl suitable manner. The upper end d of this driving-rod CZ is screw-threaded, and the nuts d2 and d3 are provided, whereby the length of the rod d maybe increased or diminished, as desired. Y

A pitman e isattached tothe driving-rod d in the usual well-known manner. The upper end of the pitman e is attached to a Wrist f. upon a driving-wheelf, keyed upon the shaft g. The shaft g is jour'naled in suitable hangers g g'. A driving-pulley g2 and loose pulley g3 are also provided upon the shaft g in the usual well-known manner. Abelt-shifting device h of the usual form is also pro- Serial No.104,142. (No model.)

vided. Upon the Vshaft g is. also placed a f wheel t', provided upon its face with a carnef. Below the cylindrical fillers b b b b isplaced a closely-fitting sliding cut-olf lo, provided with apertures k k of approximately the Same size as the mouths b b of the cylindrical filler b. Guide-bolts lo? k2 k2 in slotsin the cut-off lo are provided. I hold the sliding cnt-0E 7o closely against the mouths b b ofthe cylindrical ller b by-spriugs s s s, one end of each of which springs I attach to the tank a and the other end to the sliding cut-off k; but any other means may be provided for this purpose as desired. A spring 7c3 upon one end of the sliding cut-0E lc holds it in such position that the months b b of the vcylindrical lillers are normally open. An armZ, keyed to the vertical shaft m, is attached to the sliding cut-off 7c by the bolt l. wheelt' is provided to engage the arm m upon the vertical shaft m. A table q s provided below the fillers b b b b, having guides q' q2 on either side.

The operation of the device is as follows: The empty cans o o are placed in the tray n, which is passed between the guides q and q2 on the table q under the mouths of the cylindrical fillers b b b b. The tanka having been filled with the substance which it is desired to deposit in the cans, the shaft g is causedto rotate by the belt h and pulley g2,

causing the crank-wheel f to revolve, forcing the plungers, by means of the pit'man e and driving-rod d, to descend. It will be seen that when the ,valve-plugs p p' p p are fitted Within their respective seats pp p p by the descent of the valve-stems p2 p2 p2 p2 the shoulders p4 p4 p4 p4 on the valve-stems p2 p2 p2 p2 will engage the cross-heads p3 p3 193103 and cause the plungers to descend, forcingv the substancein the llers b b b b through the mouths b b b b of the llers b b b b and the sliding cut-oft' lo into the cans 0"0 o o on the table q, the apertures c It' in the sliding cut-off k being normally held by the spring k3 at the openings b b' in the filling-cylinders b b b b. When the plungers havedescended the full distance, the shaft g, continuing to revolve, will cause the cam rl upon the wheel t to engage thel projecting arm fm upon the vertical shaft fm, and as the arm m The cam t. upon the 1 IOO is forced out the vertical shaft m will turn, causing the arm Z, attached to the cut-oit 7c, to draw the apertures 7a' k in the sliding cuto 7c away from the mouths b b' of the filling-cylinders b b b b, thus closing the fillingcylinders. The shaft g and crank-wheel f continuing to revolve, the pitman e will be raised, drawing with it the driving-rod d, which, being attached to the valve-stems p2 p2 p2 p2, will raise the valve-plugs p p' p p'. The shoulders p5 will engage the crossheads p3 p3, respectively, and raise the plungers. The valves being open, the substance in the tank or hopper ct will be drawn down into the fillers b b b b, when the operation of discharging the fillers into the cans will be repeated, as before. The filled cans will be removed and empty cans placed under the fillers b b b ZJ atieach operation by the operator, either by hand or in any other desired manner.

I have shown two rows of four fillers each; but as many fillers may be used as may be desired.

The tank or hopper a may be filled by hand or through a pipe or in any desired manner.

The quantity of the substance which it is desired to discharge into the cans may be regulated by the nuts d2 d3 on the end of the driving-rod d.

Having thus described my invention, what I claim is- 1. In a device of the character described, the combination of a hopper, a ller attached to and opening into such hopper and provided with a mouth, a plunger within the filler, such plunger consisting of a valve-seat, a cross-head above such valve-seat and attached thereto, a valve-plug, a valve-stem attached thereto, such valve-stem being provided with a shoulder below such cross-head and engaging therewith when the valve-stem is raised, a driving-wheel, a connecting medium between such valve-stem and driving-wheel, means for rotating the driving-wheel, a wheel attached to such rotating means, a projecting cam carried by such wheel, a vertical shaft, two arms upon such vertical shaft one of such arms lying in the plane of such projecting cam, and the other arm attached to a bar provided with an aperture such bar being below the mouth of the filler and means for holding such bar normally in one position, substantially as shown and described.

2. In a device of the character described, the combination of a hopper, a iller attached to and opening into such hopper and provided With a mouth, a plunger within the filler such plunger consisting of a valve-seat, a cross-head above such valve-seatand attached thereto, a valve-plug, a valve-stem attached thereto, such valve-stem being provided with a shoulder below such cross-head and engag- Aing therewith when the valve-stem is raised,

a driving-wheel, a connecting medium between such valve-stem and driving-wheel, means between the valve-plug and drivingwheel for varying the length of such connecting medium, means for rotating the drivingwheel, a wheel attached `to suchY rotating means, a projecting cam carried by such wheel, a vertical shaft, two arms upon such vertical shaft one of such arms lying in the plane of such projecting cam, and the other arm attached to a bar provided with an aperture, such bar being below the mouth of the filler and means for holding such bar normally in one position, substantially as shown and described.

3. In a device of the character described, the combination of a cylindrical filler pro vided with a mouth, a plunger in such filler, such plunger consisting of a` valve-seat, a cross-head above the valve-seat and attached thereto, a valve-plug and a` valve-stem attached thereto, such valve-stem being provided with a shoulder below the cross-head and engaging therewith when the valve-stem is raised, means for alternately raising and lowering such valve-stem and the parts engaging therewith, a cnt-olf at thev mouth of the filler, a connecting medium between the plunger and the cut-olf for closing the mouth of the filler as the plunger israised, andfor opening the mouth of the filler as the plunger is depressed, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence ot' two subscribing witnesses.
